The Cascade Volcanic Arc SystemSeattle Annual Meeting
Newberry Volcano is the largest volcano in the Cascades volcanic arc and covers an area the size of Rhode Island (about 3100 km2 or 1200 mi2). Unlike familiar cone-shaped Cascades volcanoes, Newberry was built into the shape of a broad shield by repeated eruptions over the past 400,000 year...

Mount Shasta is estimated to have the greatest volume of any stratovolcano within the Cascade Volcanic Arc. Explore its natural wonders by hiking, river rafting, boating, mountain biking and camping. Get even closer with a side trip. The 14-mile drive on Everitt Memorial Highway (A-10) ...
volcanic[1] Detailed geologic mapping of the Klamath Falls-Keno area revealed the complex relationship between subduction, crustal extension, and magmatic composition of the southern Oregon Cascade volcanic arc. Volcanism in the study area at ~74Ma consisted of calc-alkaline basaltic andesite and ...
Here, we test the use of two large-scale atmospheric models, ERA-Interim (ERA-I) and North American Regional Reanalysis (NARR), to correct atmospheric uncertainties in InSAR data from the Cascades Volcanic Arc, United States. At Lassen Volcanic Center, we find that NARR reduces interferogram ...

the volcanic arc continues into the Coast Mountains of southwestern British Columbia, and most volcanologists consider the volcanoes here to be part of the Cascade chain. The Cascade volcanoes have formed as a result of the subduction of the Juan de Fuca, Gorda, and Explorer Plates beneath the...
The Luzon Strait in the South China Sea, another key shipping route, is the crux of all the major submerged cabling that connects China, Hong Kong, Taiwan, Japan, and South Korea. It is also encircled by the Luzon Volcanic Arc.
